There's a tiger in the garden, paperback/lizzy stewart

When Grandma says shes seen a tiger in the garden, Nora doesnt believe her.

Shes too old to play Grandmas silly games! Everyone knows that tigers live in jungles, not gardens.

  So even when Nora sees butterflies with wings as big as her arm, and plants that try and eat her toy giraffe, and a polar bear that likes fishing, she knows theres absolutely, DEFINITELY no way there could be a tiger in the garden .

Could there? Theres a Tiger in the Garden was shortlisted for The Waterstones Childrens Book Prize 2017.
